XMPlay is a skinnable audio player that plays all major audio formats and includes gapless playback, effects, equalizer, net streaming. More features are available using plugins, including visualizations, more format support, cover art and more. Note that the library and playlist will not work as you change PCs.

Can play MP3, WMA, M4A, OGG and more, as well as output to WAV, MP3 OGG etc. (via external encoders).

Alternatively, XMPlay is natively portable but does not automatically adjust library and playlist paths: download the ZIP package, extract to a folder of your choice and launch xmplay.exe.
Also, you can always download the "Latest stuff" version.

I used to use WinAmp (over the years became bloated and tool forever to load), then tried Cool Player (good, but not enough features for me). XM Player is the perfect balance - super fast, reliable (so far), flexible, and customizable. J.U.S.T. Perfect!

AIMP is a skinnable audio player similar to Winamp that supports most audio formats, as well as Internet radio. Features include a mini-player, colorizing of individual skins, equalizer, visualizations, playlist, global hotkeys, library and plug-ins capability. The application also includes a built-in tag editor, alarm clock and auto-shutdown.

smaragdus REALLY? wow I didn't realize that looks over substance was so important to sum people. Now I'm curious what others think about the "looks" of V4 or if most just don't care like me, please don't misunderstand I understand how you feel its just foreign 2me is all I'm saying. Of course if V3 suits your needs then by all means that's the correct version for you to use, no matter what I or others think. Enjoy.:)MIKLO

Foobar2000 is an audio player with low memory footprint and native support for most popular audio formats. It includes CD ripping, format conversion, replay gain, audio normalization, equalization and more. Playlist display and keyboard shortcuts are both very customizable. Additional functionality available via a wide variety of plugins.

The program can edit song tags (album and song name, number, year etc.) based on the FreeDB Internet database and even rename the original songs based on these tags. A file format conversion tool is available, but must be enabled with external downloads. Can even fix some MP3s with corrupted file headers.

Great player, especially with a few tweaks. I use Meier crossfeed[1] together with Dolby surround emulation[2]. What this does is it spreads the sound out, as if you're listening to a live performance, and greatly reduces ear strain when listening with headphones (which I do 99% of the time). Other pluses are that it uses my own music directory structure, is very fast (opens in a snap), and it uses windows native look instead of someone's idea of a great skin.

Universal Extractor 2 is an easy-to-use extraction program that works on a long list of file types including standard compression formats like ZIP, RAR, and 7Z files, as well as program installers, disk images, audio/video, and many more.
